A NOBLE IONIC PLASTIC PHASE OF CESIUM FORMATE STUDIED BY 1H, 2H AND 133CS NMR AND ELECTRICAL CONDUCTIVITY MEASUREMENTS

摘要: Abstract 1 H, 2 H and 133 Cs NMR spin-lattice relaxation times T , spin-spin in the rotating frame ϱ electrical conductivity of cesium formate were measured high-temperature cubic phase obtainable between 316K melting point (536K). The observed data attributable to anionic overall rotation self-diffusion both ions. activation energies evaluated, by applying simple Bloembergen-Purcell-Pound theory, be about 30 53 kJ mol −1 respectively, while that cationic diffusion was 45 good agreement with 47 for ionic determined measurements. From these results together thermal structural reported, it shown forms an plastic above 316 K.
